Abstract: To solve the anti-rutting gradation design problem, based on fractal theory and many experiments and calculations, a new resisting rutting gradation examination method is put forward. Based on empirical formulas of dynamic stability for asphalt mixture between asphalt penetration and gradation fractal dimension D, which is put forward, by means of binary variables curve regression through self-made MATLAB program, the method applies fractal theory to examining the aggregate gradation, by using the indices such as the fractal dimension of coarse and fine aggregate particle size distribution, the fractal void ratio of coarse aggregate, the fractal volume of fine aggregate in coarse aggregate, etc. The method solves the design blindness of mixture gradation effectively, with simple process of calculation and examination.

Key words: resisting rutting gradation, fractal theory, fractal dimension, dense skeleton type
